A Dynamic Cordon Pricing Scheme combining a Macroscopic and an Agent-based traffic Models

Pricing is considered an effective management policy to reduce traffic congestion in transportation networks. In this paper we combine a macroscopic model of traffic congestion in urban networks with an agent-based simulator to study congestion pricing sch ...

An adaptive system for real-time scalable video streaming with end- to-end qos control

Marco Mattavelli, Daniele Renzi, Beilu Shao

This paper presents a real-time adaptive video streaming system based on the latest standardized video codec H.264/MPEG-4 AVC scalable extension (SVC). The system provides a full MPEG-21 media access framework over heterogeneous networks and terminals with ...

One Bit Is Enough: a Framework for Deploying Explicit Feedback Congestion Control Protocols

Dejan Kostic, Nedeljko Vasic

Since the bandwidth-delay products of Internet links keep increasing, issues with TCP's convergence time, throughput, and amount of queuing in these environments are becoming more pressing. As we move toward the next-generation Internet, it is important to ...

A Multimedia Terminal for Adaptation and End-to-end QoS Control

Marco Mattavelli, Daniele Renzi, Beilu Shao

This paper addresses multimedia end user system design for content distribution over heterogeneous networks and terminals, with particular focus on End-to-End quality of service (QoS) control. A multimedia terminal comprising content-related metadata proce ...

Loss-resilient window-based congestion control

Pascal Frossard, Christophe De Vleeschouwer

This paper addresses the problem of fair allocation of bandwidth resources on lossy channels in hybrid heterogeneous networks. It discusses more particularly the ability of window-based congestion control to support non-congestion related losses. We invest ...

Promiting Fluidity in the Flow of Packets of 802.11 Wireless Mesh Networks

Patrick Thiran, Adel Aziz

Wireless Mesh Networks (WMNs) are based on packet forwarding and therefore require efficient multi-hop protocols for their deployment. Toward this objective, we study the flow of packets through the network and using an analogy with fluid physics we classi ...

Joint Playback Delay and Buffer Optimization in Scalable Video Streaming

Pascal Frossard, Jean-Paul Wagner

This paper addresses the problem of the transmission of scalable video streams to a set of heterogeneous clients through a common bottleneck channel. The packet scheduling policy is typically crucial in such systems that target smooth media playback at all ...

A Predictable Communication Scheme for Embedded Multiprocessor Systems

Paolo Ienne, Mehmet Harmanci, Yusuf Leblebici

Networks-on-Chip are emerging as a widely accepted alternative for the traditional bus architectures. However, their applicability by the system designers is far away from being intuitive due to their lack of predictability. This communication predictabili ...

Probabilistic Estimation of Peers’ Quality and Behaviors for Subjective Trust Evaluation

Karl Aberer

The management of trust and quality in decentralized systems has been recognized as a key research area over recent years. In this paper, we propose a probabilistic computational approach to enable a peer in the system to model and estimate the quality and ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
